Going by your words, not the paint samples, which really look different that I'd expect from the NAMES, I'd say that YES the ORCHID and the original Valspar green painted over/under on the Pansy Foret wall would be fine. There is more than one kind of balancing act going on here, and symmetrical is not required, since you hall is definitely not symmetrical. If you had doors opposite each other on the walls, then maybe symmetry in the paint job would be expected by the eye. But since the hall has an assymetrical feel to it, you can balance that feeling by putting the two colors on the wall opposite the single paint color. It will in fact make the eye feel happier with the space, even if it is not a conscious reaction. So I say GO FOR IT. It is only paint, and it can be painted over if you don't like it. A comment not about paint, but about the function of hallways in general. Nancy, you have quite a few hallways. The space is mostly just a path from one living space to another. BUT, it is space that can serve a purpose and make the hall have a real impact on the feel of size in your home. By making folks walking along the halls be distracted from their simple passage from one room to another, USE THE HALLS AS YOUR GALLERY. I would tend to have similar frames hung at the same height as the frame tops along the wall with no molding. And the wall with the molding (wainscoting height) have the pictures/frames hung same height at the bottoms. To emphasize the line of the wainscoting of course. I do not have but a simple turnaround for a hall in Mobile, just about no walls w/o door frames, so I cannot in that house create a "gallery" on the walls of the hallway. But I did it in the Cape in Mass, and in my original MoccasinLanding, AND, I painted the ceiling a sky blue with puffy white/gray clouds on it. It felt good going down that hall too. If you have a room which serves as a passage way, maybe along one side, to get to another space, that is where you can create a line of framed art, to sort of move things along. I'm putting in one picture here to show what I mean. In this small parlor, there is a path from the front door in an "L" to reach the dining room and the rest of the downstairs spaces. The "art" inside the 50% off frames (when Sears bought KMart) is just plain paper copies of pictures I took at Mystic Seaport several years ago. As a sailor, it appeals to my mind. In your case, some frames along the hallway leading up to your DH's music room would also be a prelude to music........ The long row invites a person to move in that direction, IMHO.

My hallway has our bedroom door at one end, the bathroom door on one side, and the opening to the living room on the other side (staggered, not directly across from the bathroom door), so my wall is only visible from the hallway. It's only a couple of inches from the bathroom door to the end, so I don't have room for furniture. I built narrow shelves the width of the hall, for family photos. It's easy to change out and rearrange pictures, and they are always straight! Ugh, I was pretty lopsided when I took this.

thank you both so much for the help here! @Judy Graham - great idea! definitely something we'll consider in the future as we're on a bit of a budget having invested so much with the puppy (and imagine the rugs will take some wear + tear in her younger years so want to hold off on doing anything more custom until she's older) Will save this for then!! @Beth hilarious on the kitty parkour!! I grew up with cats myself so definitely have experience with the "running starts" (and paw prints 😂!!) Thanks so much for the suggestion on the runner length - that's definitely been a hangup in my head! If we go with two 8 feet runners, we'll have a ~2 foot (tops) gap - I'm less experienced with rug placement so just wanted to get a sense of whether that sounded like a good layout? Lastly - curious on your thoughts about mixing two different designs (vs. using the same rug twice)? I'd been looking at Ruggable and LOVE their stuff (+ very pet friendly) but they unfortunately only have 7 ft + 10 ft.. assume that'd make for an awkward pairing? I tried a design tool I just found online and this looked like a good approximation for what the hallway would look like with your 8 ft rug suggestion! (definitely not the colors I'd go with, but just to get an idea!)

I can’t tell if the doors go right up to the wall however if there is space…. Small console table 10-12” in depth with a mirror above. Some decorative items. No electric but Amazon sells an adaptor light bulb to turn on a lamp where there isn’t electric or install can light. The ceiling light needs updating with similar to one in photo. This warms the space color-wise.
